Yes, mine does, that why it takes a permanent feed as well as a switched feed, lots of them do. Most cams plug into cig socket and start recording when key goes on but lots of vehicles now the cig socket is permanently live so can be an issue. The unit I bought comes in two flavours, one with a cig socket plug for basic functioning or one with a hardwire kit that enables the parking mode
When the engine goes on it starts recording, when the engine goes off it starts parking mode which records motion and impact, all timings/sensitivities are configurable in the settings and has auto off when battery voltage drops to a set voltage which you can configure
